I think we can agree the optical depth is not an issue if we are talking about a microwave spectrum that is little more than a whisper.
Considering the SED it has, no way we can agree on that.

What I am really talking about is a solar SZ effect: Inverse Compton scattering.
The upper limit on the Compton y-parameter is very strict from FIRAS. There's no evidence of it in the CMB.
